final case class Gen[-R, +A](sample: ZStream[R, Nothing, Sample[R, A]]) extends Product with Serializable

A Gen[R, A] represents a generator of values of type A, which requires an environment R. Generators may be random or deterministic.

  8. def cross[R1 <: R, B](that: Gen[R1, B]): Gen[R1, (A, B)]

    Composes this generator with the specified generator to create a cartesian product of elements.

  9. def crossWith[R1 <: R, B, C](that: Gen[R1, B])(f: (A, B) ⇒ C): Gen[R1, C]

    Composes this generator with the specified generator to create a cartesian product of elements with the specified function.

  11. def filter(f: (A) ⇒ Boolean): Gen[R, A]

    Filters the values produced by this generator, discarding any values that do not meet the specified predicate.

    Filters the values produced by this generator, discarding any values that do not meet the specified predicate. Using filter can reduce test performance, especially if many values must be discarded. It is recommended to use combinators such as map and flatMap to create generators of the desired values instead.

  23. def reshrink[R1 <: R, B](f: (A) ⇒ Sample[R1, B]): Gen[R1, B]

    Discards the shrinker for this generator and applies a new shrinker by mapping each value to a sample using the specified function.

    Discards the shrinker for this generator and applies a new shrinker by mapping each value to a sample using the specified function. This is useful when the process to shrink a value is simpler than the process used to generate it.

  24. def runCollect: ZIO[R, Nothing, List[A]]

    Runs the generator and collects all of its values in a list.

  25. def runCollectN(n: Int): ZIO[R, Nothing, List[A]]

    Repeatedly runs the generator and collects the specified number of values in a list.

  26. def runHead: ZIO[R, Nothing, Option[A]]

    Runs the generator returning the first value of the generator.

    Zips two generators together pairwise.

    Zips two generators together pairwise. The new generator will generate elements as long as either generator is generating elements, running the other generator multiple times if necessary.

  34. def zipWith[R1 <: R, B, C](that: Gen[R1, B])(f: (A, B) ⇒ C): Gen[R1, C]

    Zips two generators together pairwise with the specified function.

    Zips two generators together pairwise with the specified function. The new generator will generate elements as long as either generator is generating elements, running the other generator multiple times if necessary.
